The J.B. Field's "30 Below XLR" thermal sock is ideal for those who spend a lot of time outside in cold weather and is perfect for winter sports. With a full, heavyweight cushion and soft Merino wool, they will keep your feet warm and comfortable in the most extreme conditions.

The only differences between these thermal socks and the "30 Below Classic" are the double cuff to help socks stay up better and both ankle and arch support, which prevents slippage and bunching.

  • Content: 70% Merino Wool, 25% Nylon, 5% Spandex
  • Merino Wool for exceptional softness, moisture wicking and temperature regulation
  • Merino wool has a natural crimp in the fibre. This crimp traps body heat in air pockets around your body, keeping you warmer for longer. 
  • Double Cuff & Arch Support: Strategically placed elastic support bands where the sock is thinner: around the Arch, Ankle, and Top of the sock. Keeps the sock up for superior fit, comfort, and performance.
  • Full Cushion: Comfortable cushioning throughout the sock 
  • Impact Support Zones: Reinforced heel and toe for added durability 
  • Heavyweight: 81-148 grams(XS-XL)
  • Made proudly in Toronto, Canada!
